Use of the diagnostic FTRD®

The diagnostic FTRD® is a smaller FTRD® System for full-thickness biopsy in the colon and rectum for diagnostic purposes. It enables histology in functional diseases of the colonic wall e.g. for neuro-gastroenterological examination.

Full-thickness biopsies allow accurate histological presentation of enteric neurons and can provide important insights into the diagnosis of motility disorders.

Full-thickness biopsy  finds application in:
• hypo- and aganglionosis (e.g. Hirschsprung’s disease)
• enteric ganglionitis
• visceral neuro- and myopathy (e.g. in chronic constipation)
• gastrointestinal amyloidosis
• enteric manifestation of neurological diseases (e.g. Parkinson’s disease)

The diagnostic FTRD®

The diagnostic FTRD® consists of an application cap with a ready-to-use mounted FTRD® clip, integrated HF snare and thread. Included are the thread retriever for easy retrieval of the release thread, the endoscope sleeve with fixation tapes and FTRD® hand wheel.

For application, the application cap is mounted on the endoscope with the snare running on the outside of the scope and the sleeve preventing entrapment of any tissue between scope and snare. By turning the hand wheel, the thread is tensioned and the clip released. Using the integrated snare, the target tissue is cut above the clip.

For improved access and easier maneuverability, the diagnostic FTRD® can be used with pediatric colonoscopes ranging in diameter from 10.5 to 12.0 mm.
